GNS530/430 Approaches do not initiate properly if the initial approach point is also the go around waypoint

ISSUE DESCRIPTION

Description of the issue: When trying to activate a GPS or ILS approach by pressing activate, or activating DIR to the IAF (initial approach fix), the GNS will immediately send you to the missed approach phase if the waypoint used as IAF is also the waypoint designated to go to during a missed approach. This bug has been around for quite some time and I keep expecting someone to have reported it by now but I haven’t been able to find a bug already logged. This happens in any aircraft equipped with the GNS430 and or 530

FREQUENCY OF ISSUE

All the time, any time you activate an approach with the previously described conditions. An example approach is RNAV runway 34 at KONP

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Load an approach procedure which has a repeat of the IAF waypoint in the missed approach procedure as the waypoint to fly to when going missed

  2. Start the approach by pressing activate or DIR to the IAF.

  3. The GNS will skip all waypoints between the IAF and airport, and direct you to the missed approach waypoint. No amount of attempts DIR to the IAF will fix this, it will only let you fly the missed approach. The only way to fly the approach is to direct to a waypoint in the middle of the approach, skipping the first waypoint.

[PC Only] Are you using Developer Mode or have you made any changes to it?

No

[PC Only] What GPU (Graphics Card) do you use?

RTX4070Ti Super

[PC Only] What other relevant PC specs can you share?

I don’t think any PC specs are relevant to this bug but I am using an AMD 5800X3D on a ASUS motherboard with 32Gb of RAM.

I do have the navigraph plugin “mods” and some others which is why I am posting this in user support and not bugs. Pretty sure the issue exists without any mods but I haven’t verified.

Same here.

My workaround is to delete the last waypoint in such a situation. But I concur it’s fascinating this hasn’t surfaced somewhere else.
